Gypsum boards, also known as drywall or plasterboard, are panels made from a gypsum core that is covered with paper or fiberglass mats. The panels are used to create interior walls and ceilings in residential and commercial construction.
The gypsum core is a soft mineral composed of calcium sulphate dihydrate, which is mined from natural deposits or produced as a by-product of various industrial processes. The core is then mixed with water and additives to create a slurry, which is poured onto a sheet of paper or fiberglass mat. Another layer of paper or mat is then applied on top of the slurry, and the entire assembly is compressed and dried to form a rigid panel.
Gypsum boards are available in various sizes and thicknesses and can be easily cut, shaped, and installed using common tools and techniques. They are widely used because they are fire-resistant, soundproof, and provide a smooth and even surface for painting or wallpapering.
